This is a bit from a larger project from a few months ago (the rest of the project was done in Flash, because time constraints and audio sync). Line drawn in Pencil2D, background in MyPaint, and the rest of the color in Gimp (or maybe Krita, i don’t recall). Looking at it again i see lots that could have been improved, but i guess improvement is part of what we do =o)
